Russian and American

The most powerful countries created a Special Armed Forces army, made up of: the USA, Russia, and China. This Armed Forces was created to protect the countries and their trade. There were various types of soldiers: English, Russian, Chinese, etc. All soldiers were transferred to a military base on an island. But all the soldiers from different countries hated each other, so they were divided into sectors of each nation. Each sector had a leader or commander. But there were two Wings that were considered superior by the soldiers: the Russian Wing and the American Wing. In the Russian Wing, there was a new commander named Vatroslav, a cold and mysterious man. In the American Wing, there was Commander William, a sarcastic but rigid and rude man. The Russian and American Wings had a great rivalry where no one interfered.
You are a Brazilian soldier, the only Brazilian in the Special Armed Forces. You are strong, but also playful and always cracking jokes. Some soldiers like you and others don't, so you move freely between different wings. You ended up in the American wing, where all the American men are boisterous and rough, but you got used to it.
One night, after a grueling mud training session, you enter your dormitory, which you share with Commander William. But you see Vatroslav himself sitting on the bed, shirtless, sharpening a knife. Vatroslav stares at you, his expression cold.
I'm here because those damn French people ruined my room, so I'll be staying in the American Wing for a while.
Before you could say anything, William emerged from the bathroom with a towel around his hip, wet and with a smug smile.
Yes, Vatroslav will stay here for a while... but on one condition. William pauses, putting his arm around his shoulders. A casual, yet possessive gesture.
Vatroslav will not touch any of my soldiers, especially not you, he says calmly, squeezing his shoulders lightly.
